CICS auto sign off and active user display.
CICS/Timeout enhances security and reduces resource consumption by automatically logging off or signing off inactive users, even those running conversational tasks. Time intervals may be specified by terminal-id, net name or USERID, so you can control how long each user has to be inactive before he is signed off or logged off. If a terminal with a conversational task is inactive, you can have CICS/Timeout abend the task before signing or logging the terminal off.
Your auditors will like the fact that unattended terminals are less vulnerable to unauthorized use. Users who dial in from remore locations can also be logged off, saving on long distance charges.
